My driver side washer fluid nozzle only sprays at like 5% and the passenger is 100%?

is there a diverter or valve of sorts under the hood that diverts 50/50 to each?

or is it possible it’s just clogged with something?

Just to update, for search purposes, it wasn’t a clogged nozzle. There’s a small check valve under the middle rear of the hood that was defective.

Part number 85321-28020

It can be had on amazon for about $10 shipped. 3 minute install.

Now both sides spray as expected.

This was new to me, so I looked it up: a check valve is designed to prevent fluid back-flow when the outlet is higher than the fluid source.
In this case, to make sure the fluid stays in the lines so it emerges immediately when activating the washer fluid pump.

If it fails, it can result in uneven flow (as @Erics99RX noted) or a long delay before fluid emerges.


These are especially important for rear window washers, and I am now quite certain that my old MDX needed a new one.

I fill mine with filtered water to minimize this & spots on the glass.

Wha? Seriously?

Washer fluid is like $2 for 4L (or gallon for you US guys)... people fill it with just water?

Washer fluid spots like crazy. I fill mine with distilled water and ONR at standard wash dilution (256:1).
